Coal combustion in thermal power plants is generating ~196 millionton coal fly ash (CFA) annually. Coal is the major source of fossil fuel available all over the world in billions of tons and around 38% of the energy generated by coal. India's coal consumption will increase at an average of about % next 20 years.

6. Thermal stress. A common health risk that miners face is thermal or heat stress. "Mining environments are often very hot and humid, particularly those in outback Australia, which over time can cause thermal stress in workers. "Overexposure to heat and humidity can cause the body to become fatigued and distressed.
